Subject Re: [DISCUSS] KIP-247: Add public test utils for Kafka Streams
Date Tue, 16 Jan 2018 18:08:15 GMT
Thanks, Matthias, this looks great.

It seems like these APIs could either be used against mock objects, or against real brokers
running in the same process.  Is there a way for the user to select which they want when using
the API?  Sorry if it's in the KIP and I missed it.
